The science of pathogen transmission via the air with Prof Lidia Morawska - ACIPC conference special

38 minutes

In this third special edition from the 2021 ACIPC Conference, Brett and Martin talk to Distinguished Professor Lidia Morawska about the science of air. Lidia was named in Times magazine as one of the 100 most influential people in the world for helping highlight the airborne spread of COVID-19. Topics includes in this podcast include the science of aerosolisation from the respiratory tract, activities or source that dictate particle size and terminology around droplet and airbourne transmission.
